种植户单2000要想获得高产,其栽培技术和管理是关键。最佳的种植模式是采取稀植、足肥、壮株、争多穗、攻大穗大粒、增粒重的原则。行株距配比:行距60cm左右,株距35cm左右,留苗4.27万～4.8万株/hm~2,争取双穗率达40%以上,保证成穗在6.75万个/hm~2以上,平均每穗粒数在600粒,千粒重320g,产量就能达到1.28万kg/hm~2以上的水平,若能再强化综合管理措施,产量水平还能再提高。在生产管理中具体措施如下:
Planting a single 2000 to get high yield, its cultivation techniques and management is the key. The best planting mode is to take a thin planting, enough fat, Zhu Zhu, fight more spike, attack big spike large grain, grain weight principle. Row spacing: the spacing of about 60cm, spacing of about 35cm, seedlings 42,700 ~ 48,000 / hm ~ 2, for the double ear rate of 40% or more, to ensure that the ear is more than 67500 / hm ~ 2, an average of The number of grains per spike is 600 grains and the weight of one thousand grains is 320g. The output can reach the level of 12,800kg / hm ~ 2 or above. If comprehensive management measures can be strengthened, the output level will increase again. Specific measures in production management are as follows:
